Fully clear indoors;
but outside, they're more responsive than ever thanks to our
exclusive Chromea7™ photochromic technology. They are more
reactive to UV light so they get darker in more conditions,
including bright sun, partially sunny, cloudy, and everything in
between. They also adapt to indirect light such as light
reflected from buildings, cars, and many other surfaces.

Transitions® Signature™
lenses, are clear indoors, but outside, are more reactive to UV
light so they get darker in more conditions, such as bright sun, partial
sun, cloudy and everything in between, including indirect light to offer
prescription lens wearers a superior and enhanced way to see the world.

Transitions Signature lenses are the most balanced every day adaptive
lenses. They have the ideal combination of darkness, fast fade back
speed and indoor clarity. They provide you with optimal comfort in all
situations and temperatures, and protect against harmful UV rays.

EXCLUSIVE CHROMEA7™ TECHNOLOGYThis exclusive,
patented formulation consists of unique dyes that are integrated into
the surface of the lens. The dyes are made up of molecules that
constantly and smoothly recalibrate as the light around you changes.
They darken and lighten to just the right degree so the optimal amount
of light reaches your eyes.

The
unique characteristics of this lens responds to many different indoor
and outdoor situations that you might have with regards to a specific
life style which makes these lenses personal to your individual
lifestyles.

PHOTOCHROMIC MOLECULES CONTINUOUSLY ADJUST TO
LIGHTWhen Transitions lenses are exposed to UV light,
trillions of photochromic molecules in the lens begin to change
structure. This reaction is what causes the lenses to darken. Only
Transitions Signature lenses use exclusive Chromea7 technology, a new
formulation that allows the lenses to be more responsive than ever
before.

MORE REACTIVE TO INDIRECT LIGHT
Chromea7 technology was designed to be even more reactive to indirect
light. Indirect light can come from many sources such as light bouncing
off buildings, cars, or other surfaces or light filtering through trees
or clouds. The lenses can sense this light, even when youâ€™re facing away
from it, and adjust to the appropriate shade for your situation.

MORE RESPONSIVE IN HOTTER CLIMATESTemperature
influences the molecules in photochromic lenses; they donâ€™t get as dark
in hot climates as they would in colder weather because of how heat
interacts with the molecules. The molecules in Chromea7 technology were
structured to be more independent of temperature, which means they get
darker in hotter climates.
